POKEMON X AND Y WALKTHROUGH

Sycamore says to meet him at the "red café" that can be seen from the tower. The one he happens to mention can be found between Autumnal Avenue and Magenta Plaza. You have a conversation with Lysandre mostly about the filth in the world and get a King's Rock. Leave when they're done talking to receive another Holo Clip from Trevor who wants you to meet him and your other friends on Route 14. Skate up the avenue to North Boulevard, then go right. The tunnel to Route 14 will be on your left side.

Once there, Trevor and your Rival are discussing the Pokédex. After comparing them, your Rival challenges you to another battle. Afterwards, they all want to go to the "scary house." Follow their lead. As the path splits ahead, you can find a Cleanse Tag to the right for some relief from wild Pokémon if you're getting sick of them. The road zigzags left and right past a number of Trainers to battle. Eventually, you'll reach a large swampy clearing just before the house. A girl in the back of there has TM06 Toxic, and you'll find a small path to the right that leads to a Roseli Berry tree. On the west side is where you meet up with your friends in front of the house. Inside a man tells you a very lame story and tries to charge you for it. Tip him if you want, and you will leave. You can go through the narrow road south to find a Spell Tag, but return to the swamp and head north into town.

Laverre City

Welcome to Laverre City. The boy near the entrance has TM41 Torment to give. If you're starting to get a little tired of your clothes, you can buy some new ones here. You can fish in the pond at the center of town and find a Gengarite from a girl at the northwest corner of the city. Otherwise, aside from a few items, this town hasn't much to do. When you're ready to face the Gym Leader, proceed to the house north of the bridge.

Laverre City Pokémon Gym

This gym happens to be all fairy types. This type match-up proves to be a little more difficult than the others as Fairy has twice as many strengths than weaknesses. Furthermore, both Chesnaught and Greninja are weak to Fairy type moves. Fire, Steel, and Poison will be useful here. The place is full of teleports you need to take to get around. From the entrance, the following warps will take you to the Gym Leader:

Top Left > Bottom Left > Bottom Left > Bottom Right > Top Right

Once you reach the end, approach Leader Valerie and commence the battle.

Immediately, Val tosses a Mawile. Though a type defensive hoss, she hasn't much in overall stats and folds to Fire, a popular type. She also lacks a STAB, so use this to your advantage, and wittle her life down with weaker attacks if need be. Mr. Mime and Sylveon don't have many type weaknesses themselves but fewer resistances. Their Defence is significantly lower than their Special Defense, so choose a physical attack over anything else.

Poison and Steel are both effective here. Doublade/Aegislash is good to have for this fight, as well as Skrelp which you can catch along Route 8 or its adjoining cities with a Good Rod in Pokemon Y only. It is recommended that you leave any of your Fighting types on the bench.

Your reward for dispatching this foe is, of course, the Fairy Badge. You now have the right to command Lv 80 Pokémon and own TM99 Dazzling Gleam. After you two have finished talking, head through the green portal and strut out to town. Shauna and Trevor meet you outside to direct you to the Pokéball Factory due north. Start there next.
